SPECIFICATION forming part of Letters Patent No. 689,091, dated December17, 1 01.

Application filed December 10. 1900. Serial No. 39,282. [No model.)

metal have had an enlarged diameter and an nular shoulders on the insideand outside at one end of the pipe, so that the straight and plain endof another piece could be inserted in the enlarged end and cement ormolten lead placed around the pipes to make a water-tight joint. Pipesthus formed and conneeted for conveying sewage, water, or any other kindof fluid matter when the ground settles under them are liable to sag andin bending downward at the joints to break the cement and to separate tosome degree, so as to cause leakage between the overlying or telescopicparts. Semicireular extensions have also been formed on the enlargedends of pipes, so the end of a pipe of smaller dimensions could be byvertical motion placed on the inside surface of the semicircularextension and a water-tight joint produced between the two ends by meansof packing and cement; but in no instance has a semicircular extensionof the enlarged end of a pipe been provided with a groove on its insideface and the small end of the pipe provided with an integral beadadapted to enter the groove in the enlarged extension of another likepiece of pipe to prevent any longitudinal movement between the overlyingparts and to aid in producing a water-tight and durable joint ascontemplated by my invention.

My object is to facilitate the labor required in connecting pieces ofpipe and to prevent the breaking, leaking, and damages incident to thesagging and separating of continuous pipes at the points where they arecoupled together to produce water-tight joints; and my inventionconsists in the construction and combination of mating pieces of pipe,as hereinafter set forth, pointed out in my claims, and illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view of ashort section of pipe that may be made of clay or any other suitablematerial and vary in length, diameter, and weight as desired. Fig. 2shows two mating pieces connected and in position as required to preventdeflection from a straightline, as occurs when there is sagging,separation, and impairment of a joint in a line of pipe. Fig. 3 is alongitudinal central sectional view of the joint shown in Fig. 2. Dottedlines indicate where cement is applied, so that it will be visible onthe exterior and where it will. not be broken by sagging of a pipe andremain intact, as required to maintain a water-tight and steamtightjoint.

The letter A designates the central body portion of a piece or completesection of my pipe.

B is the end that has an enlarged diameter, an annular shoulder O on itsexterior, and an annular shoulder D at the inner end of the bore ofenlarged diameter.

F is an integral semicircular extension of the part B, and H is a groovein the inside face and rear end of the extension adapted to admit acorresponding bead on the straight end of a mating length or section ofpipe, as shown in Fig. 3.

J is an integral bead on y the small and straight end of the section solocated relative to the extension F and the groove H that when twosections are connected to produce a joint the end face of the straightend will abut against the annular shoulder D at the inner end of theenlarged diameter and the bead J will be in the groove F, so that thepieces will be practically interlocked, as required to preventlongitudinal movements relative to each other to prevent sagging at ajoint, breakage, and leakage.

In laying pipes and connecting sections it is obvious that when onepiece or section is in proper position the straight and small end of amating section when the bead J is on top can be first readily placedupon the end portion of the semicircular extension F and then movedlongitudinally and into the bore of enlarged diameter and then byrotating it a half revolutioueause the beadJ to enter the groove H.Strong and durable joints thus readily produced can very quickly be madewater-tight and steam-tight by applying suitable cement or metal on topof the straight and small end and against the face of the large end, asindicated by dotted lines in Fig. 3.

Having thus described the purpose and construction of my invention, itspractical utility will be readily understood by persons familiar withthe art to which it pertains, and What I claim as new, and desire tosecure by Letters Patent, is

1. A section of pipe having an enlarged diameter at one end, an annularshoulder at the inner end of the enlarged bore, a semicircular extensionat the end of the enlarged portion, a groove in the inside face of saidextension and a bead on the exterior of the small and straight end ofthe same pipe, for the purposes stated.

2. In a pipe composed of mating sections, a joint consisting of asection having an extension of enlarged diameter at one end, asemicircular extension of the enlarged portion and a groove in theinside face of said semicircular extension and a pipe-section having astraight end fitted in the bore of said enlarged diameter and providedwith an integral bead on its outer surface adapted to enter said groovein the semicircular extension, arranged and combined in the manner setforth for the purposes stated.
